According to Tuckman, these three criteria should be kept in mind before stating a hypothesis –
A good hypothesis statement should
'My assumption is that tomorrow Mary will bring snacks for all'.
Assumption and hypothesis often create confusion as both are widely used in the field of research. An assumption is about taking things for granted, without having any firm explanation behind it. On the other hand, hypothesis is a type of assumption for a certain purpose of argument. However, both are not already proved. An assumption is always assumed to be true. On the other hand, a hypothesis is regarding statements that need certain investigation. In research, assumptions are formulated and on the basis of the assumptions certain hypothesis statements are declared. Thus, a hypothesis can also be considered as an assumption that is taken to be true unless proven otherwise.

Definition | A Hypothesis is an uncertain explanation regarding a phenomenon or event. It is widely used as a base for conducting tests and the results of the tests determine the acceptance or rejection of the hypothesis. | An assumption is also a kind of belief which is considered to be true. An assumption may or may not be verified or investigated. In research, assumption denotes the existence of the relationship between the variables. |
Origin | The term derives from the Greek, hypotithenai meaning "to put under" or "to suppose." | from Late Latin assumption-, assumptio taking up, from Latin assumere. |
Proving methodology | Various experiments can lead to various results. Thus a hypothesis can be proved or rejected depending upon the method used by the scientists. | General assumptions may or may not require any methods for verification or acceptance. Research assumptions are generally proved by forming hypothesis based on them. |
Supported by Reasoning | Yes | Usually |
Example | The higher time the students spend on their studies, the better they achieve tests and score better marks. | There is a correlation between the time period to study and marks attained. |

The hypothesis is a common term in Machine Learning and data science projects. As we know, machine learning is one of the most powerful technologies across the world, which helps us to predict results based on past experiences. Moreover, data scientists and ML professionals conduct experiments that aim to solve a problem. These ML professionals and data scientists make an initial assumption for the solution of the problem. This assumption in Machine learning is known as Hypothesis. In Machine Learning, at various times, Hypothesis and Model are used interchangeably. However, a Hypothesis is an assumption made by scientists, whereas a model is a mathematical representation that is used to test the hypothesis. In this topic, "Hypothesis in Machine Learning," we will discuss a few important concepts related to a hypothesis in machine learning and their importance. So, let's start with a quick introduction to Hypothesis. It is just a guess based on some known facts but has not yet been proven. A good hypothesis is testable, which results in either true or false. : Let's understand the hypothesis with a common example. Some scientist claims that ultraviolet (UV) light can damage the eyes then it may also cause blindness. In this example, a scientist just claims that UV rays are harmful to the eyes, but we assume they may cause blindness. However, it may or may not be possible. Hence, these types of assumptions are called a hypothesis. The hypothesis is one of the commonly used concepts of statistics in Machine Learning. It is specifically used in Supervised Machine learning, where an ML model learns a function that best maps the input to corresponding outputs with the help of an available dataset. There are some common methods given to find out the possible hypothesis from the Hypothesis space, where hypothesis space is represented by and hypothesis by Th ese are defined as follows: It is used by supervised machine learning algorithms to determine the best possible hypothesis to describe the target function or best maps input to output. It is often constrained by choice of the framing of the problem, the choice of model, and the choice of model configuration. . It is primarily based on data as well as bias and restrictions applied to data. Hence hypothesis (h) can be concluded as a single hypothesis that maps input to proper output and can be evaluated as well as used to make predictions. The hypothesis (h) can be formulated in machine learning as follows: Where, Y: Range m: Slope of the line which divided test data or changes in y divided by change in x. x: domain c: intercept (constant) : Let's understand the hypothesis (h) and hypothesis space (H) with a two-dimensional coordinate plane showing the distribution of data as follows: Hypothesis space (H) is the composition of all legal best possible ways to divide the coordinate plane so that it best maps input to proper output. Further, each individual best possible way is called a hypothesis (h). Hence, the hypothesis and hypothesis space would be like this: Similar to the hypothesis in machine learning, it is also considered an assumption of the output. However, it is falsifiable, which means it can be failed in the presence of sufficient evidence. Unlike machine learning, we cannot accept any hypothesis in statistics because it is just an imaginary result and based on probability. Before start working on an experiment, we must be aware of two important types of hypotheses as follows: A null hypothesis is a type of statistical hypothesis which tells that there is no statistically significant effect exists in the given set of observations. It is also known as conjecture and is used in quantitative analysis to test theories about markets, investment, and finance to decide whether an idea is true or false. An alternative hypothesis is a direct contradiction of the null hypothesis, which means if one of the two hypotheses is true, then the other must be false. In other words, an alternative hypothesis is a type of statistical hypothesis which tells that there is some significant effect that exists in the given set of observations.The significance level is the primary thing that must be set before starting an experiment. It is useful to define the tolerance of error and the level at which effect can be considered significantly. During the testing process in an experiment, a 95% significance level is accepted, and the remaining 5% can be neglected. The significance level also tells the critical or threshold value. For e.g., in an experiment, if the significance level is set to 98%, then the critical value is 0.02%. The p-value in statistics is defined as the evidence against a null hypothesis. In other words, P-value is the probability that a random chance generated the data or something else that is equal or rarer under the null hypothesis condition. If the p-value is smaller, the evidence will be stronger, and vice-versa which means the null hypothesis can be rejected in testing. It is always represented in a decimal form, such as 0.035. Whenever a statistical test is carried out on the population and sample to find out P-value, then it always depends upon the critical value. If the p-value is less than the critical value, then it shows the effect is significant, and the null hypothesis can be rejected. Further, if it is higher than the critical value, it shows that there is no significant effect and hence fails to reject the Null Hypothesis. In the series of mapping instances of inputs to outputs in supervised machine learning, the hypothesis is a very useful concept that helps to approximate a target function in machine learning. It is available in all analytics domains and is also considered one of the important factors to check whether a change should be introduced or not. It covers the entire training data sets to efficiency as well as the performance of the models. Hence, in this topic, we have covered various important concepts related to the hypothesis in machine learning and statistics and some important parameters such as p-value, significance level, etc., to understand hypothesis concepts in a better way. |

thesis hypothesis and theory
Many students may have a hard time understanding the differences between a thesis, a hypothesis, and a theory. It is important to understand their differences. Such an understanding will be instrumental.
More so, when writing complex research papers that require a thesis that has a hypothesis and utilizes theories. We have gathered from responses of our college writing service that the difference between the three is confusing.
That being said, this article is meant to explain the differences between a thesis, a hypothesis, and a theory.
There are major differences between hypothesis and thesis. While they seem to be related on the face, their differences are huge both in concept and practice.
A hypothesis is a proposed explanation of something or a phenomenon. A scientific hypothesis uses a scientific method that requires any hypothesis to be tested. As such, scientists and researchers base their hypothesis on observations that have been previously made and that which cannot be explained by the available or prevailing scientific theories.
From the definition of a hypothesis, you can see that theories must be included in any scientific method. This is the reason why this article tries to differentiate a thesis, a hypothesis, and a theory.
Moving forward, a thesis can be defined as a written piece of academic work that is submitted by students to attain a university degree. However, on a smaller scale, there is something that is referred to as a thesis statement.
This is written at the introduction of a research paper or essay that is supported by a credible argument. The link between a hypothesis and thesis is that a thesis is a distinction or an affirmation of the hypothesis.
What this means is that whenever a research paper contains a hypothesis, there should be a thesis that validates it.

A hypothesis can be defined as the proposed or suggested explanation for an occurrence, something, or a phenomenon. It should be testable through scientific methods. The reason why scholarly works should have a hypothesis is that the observed phenomena could not be explained using the prevailing scientific theories hence the reason why it should be tested.
Testing the hypothesis may result in the development of new or improved scientific theories that are beneficial to the discipline and society in general.
A thesis is a written piece of academic work that is submitted by students to attain a university degree. When a thesis is used as a stand-alone word, it denotes academic papers written by university students. It is mostly written by those pursuing postgraduate degrees, at the end of their courses. They demonstrate their proficiency in their disciplines and the topics they have selected for research.
However, when a thesis is used to refer to a statement, it denotes the statement that is written at the introduction of a research paper or essay. A thesis is supported by a credible argument.
Every research paper must have a thesis statement that acts as a guide to what the research will be all about. It is possible to receive very poor grades or even score a zero if your research paper lacks the thesis statement.
A theory can be defined as a rational form of abstract perspectives or thinking concerning the results of such thinking or a phenomenon. The process of rational and contemplative thinking is mostly associated with processes such as research or observational study.
As such, a theory can be considered to belong to both scientific and non-scientific disciplines. Theories can also belong to no discipline.
From a modernistic scientific approach, a theory can mean scientific theories that have been well confirmed to explain nature and that are created in such a way that they are consistent with the standard scientific method. A theory should fulfill all the criteria required by modern-day science.
A theory should be described in a way that scientific tests that have been conducted can provide empirical support or contradiction to the theory.
Because of the nature by which scientific theories are developed, they tend to be the most rigorous, reliable, and comprehensive when it comes to describing and supporting scientific knowledge.
The connection between a theory and a hypothesis is that when a theory has not yet been proven, it can be referred to as a hypothesis.
The thing about theories is that they are not meant to help the scientist or researcher reach a particular goal. Rather, a theory is meant to guide the process of finding facts about a phenomenon or an observation.

A theory is a rational form of abstract perspectives or thinking concerning the results of such thinking or a phenomenon. The process of rational and contemplative thinking is mostly associated with processes such as research or observational study. On the other hand, a thesis is a written piece of academic work that is submitted by students to attain a university degree.
It denotes academic papers that are written by students in the university, especially those pursuing postgraduate degrees, at the end of their courses to demonstrate their proficiency in their disciplines and the topics they have selected for research.
To understand the application of these, read our guide on the difference between a research paper and a thesis proposal to get a wider view.
1. asking a question.
Asking a question is the first step in the scientific method and the question should be based on who, what, where, when, why, and how . The question should be focused, specific, and researchable.
This is the process of collecting relevant data. It can be done by researching academic journals, conducting case studies, observing phenomena, and conducting experiments.
When the research is completed, you should think of how best to answer the question and defend your position. The answer to your question should be objective.
When your answer is ready, you can move to the next step of formulating the hypothesis. A good hypothesis should contain relevant variables, predicted outcomes, and a study group that can include non-human things. The hypothesis should not be a question but a complete statement.
Though you may skip this step, it is advisable to include it because your study may involve two groups or be a correlational study. Refining the hypothesis will ensure that you have stated the difference or relationship you expect to find.
A null hypothesis (H0) will postulate that there is no evidence to support the difference. On the other hand, an alternative hypothesis (H1) posits that there is evidence in support of the difference.

A summary is a brief account or statement of the main points from the researches. A thesis statement is a statement that is written at the end of the introduction of a research paper or essay that summarizes the main claims of the paper.
A hypothesis can be defined as the proposed or suggested explanation for an occurrence, something, or a phenomenon. The same should be testable through scientific methods. Conversely, a statement of a problem is a concise description of the issue to be addressed on how it can be improved.

A hypothesis is used in an experiment to define the relationship between two variables. The purpose of a hypothesis is to find the answer to a question. A formalized hypothesis will force us to think about what results we should look for in an experiment. The first variable is called the independent variable.
What is a hypothesis and what form does it take?
A hypothesis is usually written in the form of an if/then statement, according to the University of California. This statement gives a possibility (if) and explains what may happen because of the possibility (then). The statement could also include “may.”
A hypothesis has classical been referred to as an educated guess. When we use this term we are actually referring to a hypothesis. For example, someone might say, “I have a theory about why Jane won’t go out on a date with Billy.” Since there is no data to support this explanation, this is actually a hypothesis.
What is the basic format of the hypothesis?
Here are examples of a scientific hypothesis. Although you could state a scientific hypothesis in various ways, most hypotheses are either “If, then” statements or forms of the null hypothesis. The null hypothesis is sometimes called the “no difference” hypothesis.
However, there are some important things to consider when building a compelling hypothesis.
What is hypothesis in research paper?
A research hypothesis is a statement of expectation or prediction that will be tested by research. Before formulating your research hypothesis, read about the topic of interest to you. In your hypothesis, you are predicting the relationship between variables.
A hypothesis often follows a basic format of “If {this happens} then {this will happen}.” One way to structure your hypothesis is to describe what will happen to the dependent variable if you make changes to the independent variable.
What is research hypothesis example?
For example, a study designed to look at the relationship between sleep deprivation and test performance might have a hypothesis that states, “This study is designed to assess the hypothesis that sleep-deprived people will perform worse on a test than individuals who are not sleep-deprived.”
How to Formulate an Effective Research Hypothesis
How do you start a hypothesis?
Examples of Hypothesis: If I replace the battery in my car, then my car will get better gas mileage. If I eat more vegetables, then I will lose weight faster. If I add fertilizer to my garden, then my plants will grow faster. If I brush my teeth every day, then I will not develop cavities. If I take my vitamins every day, then I will not feel tired.
How do you propose a hypothesis?

In statistical hypothesis testing, the alternative hypothesis is an important proposition in the hypothesis test. The goal of the hypothesis test is to demonstrate that in the given condition, there is sufficient evidence supporting the credibility of the alternative hypothesis instead of the default assumption made by the null hypothesis.
Alternative Hypotheses
Both hypotheses include statements with the same purpose of providing the researcher with a basic guideline. The researcher uses the statement from each hypothesis to guide their research. In statistics, alternative hypothesis is often denoted as H a or H 1 .

“A hypothesis is a statement of a relationship between two or more variables.” It is a working statement or theory that is based on insufficient evidence.
While experimenting, researchers often make a claim, that they can test. These claims are often based on the relationship between two or more variables. “What causes what?” and “Up to what extent?” are a few of the questions that a hypothesis focuses on answering. The hypothesis can be true or false, based on complete evidence.
While there are different hypotheses, we discuss only null and alternate hypotheses. The null hypothesis, denoted H o , is the default position where variables do not have a relation with each other. That means the null hypothesis is assumed true until evidence indicates otherwise. The alternative hypothesis, denoted H 1 , on the other hand, opposes the null hypothesis. It assumes a relation between the variables and serves as evidence to reject the null hypothesis.
Example of Hypothesis:
Mean age of all college students is 20.4 years. (simple hypothesis).
An Alternative Hypothesis is a claim or a complement to the null hypothesis. If the null hypothesis predicts a statement to be true, the Alternative Hypothesis predicts it to be false. Let’s say the null hypothesis states there is no difference between height and shoe size then the alternative hypothesis will oppose the claim by stating that there is a relation.
We see that the null hypothesis assumes no relationship between the variables whereas an alternative hypothesis proposes a significant relation between variables. An alternative theory is the one tested by the researcher and if the researcher gathers enough data to support it, then the alternative hypothesis replaces the null hypothesis.
Null and alternative hypotheses are exhaustive, meaning that together they cover every possible outcome. They are also mutually exclusive, meaning that only one can be true at a time.
There are a few types of alternative hypothesis that we will see:
1. One-tailed test H 1 : A one-tailed alternative hypothesis focuses on only one region of rejection of the sampling distribution. The region of rejection can be upper or lower.
2. Two-tailed test H 1 : A two-tailed alternative hypothesis is concerned with both regions of rejection of the sampling distribution.
3. Non-directional test H 1 : A non-directional alternative hypothesis is not concerned with either region of rejection; rather, it is only concerned that null hypothesis is not true.
4. Point test H 1 : Point alternative hypotheses occur when the hypothesis test is framed so that the population distribution under the alternative hypothesis is a fully defined distribution, with no unknown parameters; such hypotheses are usually of no practical interest but are fundamental to theoretical considerations of statistical inference and are the basis of the Neyman–Pearson lemma.
the differences between Null Hypothesis and Alternative Hypothesis is explained in the table below:
Null Hypothesis(H ) | Alternative Hypothesis(H ) | |
---|---|---|
Definition | A default statement that states no relationship between variables. | A claim that assumes a relationship between variables. |
Denoted by | H | H or H |
In Research | States a presumption made before-hand | States the potential outcome a researcher may expect |
Symbols Used | Equality Symbol (=, ≥, or ≤) | Inequality Symbol (≠, <, or >) |
Example | Experience matters in a tech-job | Experience does not matter in a tech-job |
Formulating an alternative hypothesis means identifying the relationships, effects or condition being studied. Based on the data we conclude that there is a different inference from the null-hypothesis being considered.
Alternative hypothesis must be true when the null hypothesis is false. When trying to identify the information need for alternate hypothesis statement, look for the following phrases:
When alternative hypotheses in mathematical terms, they always include an inequality ( usually ≠, but sometimes < or >) . When writing the alternate hypothesis, make sure it never includes an “=” symbol.
To help you write your hypotheses, you can use the template sentences below.
Does independent variable affect dependent variable?
Various examples of Alternative Hypothesis includes:
Two-Tailed Example
One-Tailed Example
Some applications of Alternative Hypothesis includes:
We defined the relationship that exist between null-hypothesis and alternative hypothesis. While the null hypothesis is always a default assumption about our test data, the alternative hypothesis puts in all the effort to make sure the null hypothesis is disproved.
Null-hypothesis always explores new relationships between the independent variables to find potential outcomes from our test data. We should note that for every null hypothesis, one or more alternate hypotheses can be developed.

What is hypothesis.
A hypothesis is a statement of a relationship between two or more variables.” It is a working statement or theory that is based on insufficient evidence.
Alternative hypothesis, denoted by H 1 , opposes the null-hypothesis. It assumes a relation between the variables and serves as an evidence to reject the null-hypothesis.
Null hypothesis is the default claim that assumes no relationship between variables while alternative hypothesis is the opposite claim which considers statistical significance between the variables.
Null hypothesis (H 0 ) states there is no effect or difference, while the alternative hypothesis (H 1 or H a ) asserts the presence of an effect, difference, or relationship between variables. In hypothesis testing, we seek evidence to either reject the null hypothesis in favor of the alternative hypothesis or fail to do so.

Legal language, or “legalese”, is notoriously hard to understand. Legalese contains more difficult linguistic structures and unusual word choices than most other styles of writing, including non-fiction, news media and even complex academic texts.
The convoluted structure of many legal sentences can make it tough to understand and remember legal obligations. Even lawyers don’t like legal language . So why does it work this way?
In a new study with my colleagues Eric Martínez (University of Chicago) and Edward Gibson (MIT), we found that even laypeople resort to legalese when asked to write laws – which suggests the complexity of legal language may be a kind of ritual that helps give the law its power.
One of the main reasons readers struggle with legal texts is a particular linguistic feature called “centre embedding”.
Centre embedding occurs when one sentence is placed inside another sentence. For example, in the sentence “ the cat that chased the mouse avoided the dog ” the sentence “ the cat chased the mouse ” is placed into the middle of the sentence “ the cat avoided the dog ”.
While this example sentence is fairly short, the sentences in legalese are often much longer. Take for example this drunk-driving law from Massachusetts, in which we bold the main sentence:
Whoever , upon any way or in any place to which the public has a right of access, or upon any way or in any place to which members of the public have access as invitees or licensees, operates a motor vehicle with a percentage, by weight, of alcohol in their blood of eight one-hundredths or greater, or while under the influence of intoxicating liquor, or of marijuana, narcotic drugs, depressants, or stimulant substances, all as defined in section one of chapter ninety-four C, or while under the influence from smelling or inhaling the fumes of any substance having the property of releasing toxic vapors as defined in section 18 of chapter 270 shall be punished by a fine of not less than five hundred nor more than five thousand dollars or by imprisonment for not more than two and one-half years, or both such fine and imprisonment .“
Centre-embedded sentences are difficult to process because readers have to remember what happened in the outside (bold) sentence while they’re reading the inside sentence. The reading difficulty increases with the distance between the words that depend on each other. (In the quoted sentence above, that’s ” Whoever “ and ” shall “.)
In our new study , we analysed the 2021 edition of the US legal code, the official compilation of all federal legislation currently in force. We then compared the results with other genres in a representative body of writing in English.
We found centre embedding is far more common in these laws than in other kinds of text.
We also found the "dependency length” – the distance between words that depend on each other – was also much longer.
In the United States (and elsewhere), there have been repeated efforts to write laws in “plain language”. However, our earlier research has found that the prevalence of centre embedding and other difficult linguistic structures in US law has changed little since at least 1950.
Why is legal language so resistant to change? To find out, we need to know why lawyers are using legalese in the first place.
Perhaps laws written in legalese are more enforceable than simpler texts, or maybe writing in complex language improves a lawyer’s career prospects or makes clients trust them more. These don’t seem to be the case.
Research has shown that lawyers believe texts written in legalese are no more enforceable than plain-English texts with the same content. They also believe using plain English is likely to improve their career prospects and make clients happier.
We also investigated two more possible reasons for using legalese.
The first is the “copy and edit” hypothesis: because legal contracts often address similar circumstances to other contracts, lawyers may copy templates and simply edit the details. Difficult structures such as centre embedding might be unconsciously copied in the template, or added as the lawyer iteratively edits drafts for their client.
The second is the “magic spell” hypothesis. Much like a magic spell, the purpose of legal language is to change the world rather than simply describe it.
This kind of “performative language” is often accompanied by a ritual or some distinctive linguistic feature. Magic spells, for instance, might be highlighted with rhyme (“double, double, toil and trouble”) or archaic roots (“wingardium leviosa”).
According to this hypothesis, difficult structures such as centre embedding may be used to highlight the performative nature of legal text.
To test these hypotheses, we provided a group of 286 non-lawyers the legal content from US laws and asked them to write either laws, stories about breaking the law, or helpful explanations of a law to a tourist.
For half of the trials, the complete legal content was provided to the participant from the start. On the other trials, we hid some of the legal content from participants at first. After they submitted a draft, we surprised them with additional content to mimic the editing process of lawyers.
In line with the magic spell hypothesis, participants used more centre-embedded structures writing laws than when writing stories or explanations of laws. In contrast with the copy-and-edit hypothesis, participants did not include more centre embedding when they were asked to edit their text than when writing from scratch.
These results suggest that the difficulty to process linguistic structures in legal text, like centre embedding, serve as a cue to the performative, world-altering, nature of the text.
If laws really are like magic spells, it’s good news for simplifying legal language. If the difficult linguistic structures in legal language are there to highlight the performative nature of the text, we should be able to choose a new linguistic feature as a marker.
And maybe this time it will be one that works alongside plain English to help people understand legal obligations.

Examples of hypotheses The following are some examples of hypotheses along with their classifications: If an office provides snacks, employees will take fewer off-site breaks: This is a simple hypothesis, as the independent variable is providing snacks at the office and the dependent variable is whether fewer employees choose to take an off-site break.
15 Hypothesis Examples. A hypothesis is defined as a testable prediction, and is used primarily in scientific experiments as a potential or predicted outcome that scientists attempt to prove or disprove (Atkinson et al., 2021; Tan, 2022). In my types of hypothesis article, I outlined 13 different hypotheses, including the directional hypothesis ...
In the above example, we have multiple independent and dependent variables: Independent variables: Age and weight. Dependent variables: diabetes and heart disease. Because there are multiple variables, this study is a lot more complex than a simple hypothesis.It quickly gets much more difficult to prove these hypotheses.

A hypothesis is a single sentence answer to the Key Inquiry Question that clearly states what your entire essay is going to argue. It contains both the argument and the main reasons in support of your argument. Each hypothesis should clearly state the 'answer' to the question, followed by a 'why'. For Example:
A hypothesis is a statement you can approve or disapprove. You develop a hypothesis from a research question by changing the question into a statement.

We might know that X leads to Y, but a mediation hypothesis proposes a mediating, or intervening variable. That is, X leads to M, which in turn leads to Y. In the diagram below I use a different way of visually representing things consistent with how people typically report things when using path analysis. I use mediation a lot in my own research.
Hypothesis is a prediction of the outcome of a study. Hypotheses are drawn from theories and research questions or from direct observations. In fact, a research problem can be formulated as a hypothesis. To test the hypothesis we need to formulate it in terms that can actually be analysed with statistical tools.
Hypothesis Statements - Overview and Template This document contains definitions, examples, and a template to complete for your assignment. Hypothesis Statements Overview A hypothesis is a prediction about the relationship between two variables. Hypotheses statements often start as an educated guess about how one variable affects a second variable. A hypothesis statement must be testable (i.e ...
A hypothesis is a function that best describes the target in supervised machine learning. The hypothesis that an algorithm would come up depends upon the data and also depends upon the restrictions and bias that we have imposed on the data. The Hypothesis can be calculated as: y = mx + b y =mx+b. Where, y = range. m = slope of the lines.
Null hypothesis, often denoted as H0, is a foundational concept in statistical hypothesis testing. It represents an assumption that no significant difference, effect, or relationship exists between variables within a population.

Hypothesis Definition. In the context of a consulting interview, a hypothesis definition is "a testable statement that needs further data for verification". In other words, the meaning of a hypothesis is that it's an educated guess that you think could be the answer to your client's problem. A hypothesis is therefore not always true.
A hypothesis is an uncertain or supposition explanation regarding a phenomenon or event. It is believed to be true by the researcher. An assumption is also a kind of belief which is considered to be true. hypothesis must always go through the process of verification and investigation. On the other hand, an assumption may or may not be verified or investigated.
